FIRE-BOX FOR STOVES, RANGES, 80C.

SPECIFICATION forming part of Letters Patent No. 643,430, dated February13, 1900.

Application filed July 11, 1898. Serial No. 685,613. (No model.)

To all whom t may concern: j

Be it known that we, HENRY J. VARREN and CARL NORDELL, of Stamford, inthe county of Fairfield and State of Connecticut, have invented certainnew and useful Improvements in Fire-Boxes for Stoves, Ranges,&c., ofwhich i the followingis a full, clear, and exact description.

This invention relates to fire-boxes, but more particularly to{ire-boxes for ranges and cooking-stoves.

The primary object of the invention is to provide a simple and efficientsectional frame whereby the usual fire-bricks may be protected andretained in position in the fire-box and in case of injury to the frameone or more parts thereof may be removed and repaired or other pieces orsections substituted therefor with very little trouble, therebydispensing with the usual brick-rest or grate-frame and overcoming manyof the objectionable features incident to devices of this character asordinarily constructed.

Other objects are to provide means which will permit various forms ofgrate-bars to be employed, to provide means which will allow properexpansion of the part-s, and to provide a sectional frame which isadapted for use in connection with various forms of stoves, ranges, dce.

The invention Will be hereinafter more particularly described withreference tol the accompanying drawings, which form a part of thisspecication, and then pointedV out in the claims at the end of thedescription.

In the drawings,wherein similar numerals of reference indicate similarparts, Figure 1 is a vertical sectional View, partly in elevation, ofone form of range with the invention applied thereto, the section beingtaken on the line I I ofFig. 2. Fig. 2 is a sectional plan, on a largerscale, partly broken away, taken on the line ,II II of Fig. 1. Fig. 3 isa fragmentary vertical section through the fire-box, taken on the lineIII IH of Fig. 2, the pitchline only of the gears connecting the shaftsof the grate-sections heilig shown. Fig. 4c is a fragmentary verticalsection taken on the line IV 1V of Fig. 2. Fig. 5 is a fragmentarysectional planl taken on the line V V of Fig. 4; and Fig. 6 is a detailperspective view, partly broken away, of a portion of the sectionalframe.

The casing 10 may support the usual cover or top for cooking utensilsand is provided With a suitable fire-box 10% This {ire-box hassuitablelugs 11, adapted to support the bricks 12, which have theirlower ends rabbeted, so as to fit upon and between said lugs. A plate 18may have its upper end secured to the casing 10 and its lower end madeangular to support the end brick or bricks 14. The features thus fardescribed, either in part or as an entirety, may be of any preferredform or construction.

For the purpose of retaining the fire-bricks in their proper positionand to preventinjury to the lower edges thereof by the coal and topermit the parts to be readily removed or repaired a sectional frame, as15, is preferably arranged beneath the bricks. As shown, this frame hasan end section or bar 15a, provided with a flange 16, which is adaptedto iit in a recessed edge of the brick or bricks above the same and hasits outer ends rabbeted or recessed, as at 17, so as to be removablyengaged by the sections or bars 18. The sections 18 have iianges 19,similar to the iiange 16 of the end section,which fit recesses in thelower edges of the bricks and have their ends 20 L-shaped or otherwiseformed and adapted to rest upon the base-plates 21 of the bracket 22.The base-plates of the bracket, Figs. 2, 3, and 6,- have holes orapertures therein, through which pass the screw-bolts 23, the latterserving to rigidly hold the bracket to slotted ears or lugs 24 on theiire-boX casing. This bracket has the standards 25, whichsupport theguard-bar 26 and serve to limit the outward movement of the .ends of theside sections 18. The guardbar 26 abuts against a pendent flange 26a onthe plate 13, which latter, together with the flange thereon, serves toprotect the gears 27 from the heat as much as possible, the gears beingrigidly held to the shafts 2S, and 28a,

one of which, as 28, has a polygonal end to permit it to be turned torotate the shafts in unison in the usual manner. The shafts of thegrates have one of their ends supported in a hanger or spacing-bar 29,so as'to pass beneath the guard-bar 26 of the bracket 22,

said hanger serving as a spacing and locking barand havin g aperturedends,throu gh which pass pins or bolts 30,whieh engage apertures in thebase-plates 2l of the bracket to removably hold the hanger to saidbracket, the ends of the hanger being adapted to engage the inner edgesof the side sections, so as to rigidly and removably hold the sameapart. By this means the parts areinterloeked, and the end and sidesections of the frame are locked together and to the bracket, thoughinstead of the bracket being fastened it may be arranged in any suitablemanner and the end and side sections of the frame made to interlock witheach other and be held in the fire-box, as desired.

The shafts 28 and 28 have the hubs 30 of the gears 27 secured theretoand have one of their ends supported in the hanger or locking-bar 29 andtheir other ends supported in the hanger 3l, which is secured to theeasing by the bolts The hanger 29, as well as the hanger 3l, may have anintermediate socket 33 to permit either single or duplex gratos to beemployed. These features are only referred to generally herein and formsubject-matter for a divisional application filed March 10,1899, SerialNo. 708,592.

The invention will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings.

lf the frame or any part thereof is to be removed, the pins 30 aredisengaged from the base-plates of the bracket 22 and the hanger 29foreedoutwardly through the opening in the fire-box easing. Thisreleases the ends 2O of the side sections or bars 1S and will permit thegrate-bar shafts to be lowered in the hanger 3l or removed. The ends 2Oof the sections 1S may be forced inwardly, which will permit them to bewithdrawn through the opening in the easing and will leave the endsection or bar l5 free to be withdrawn, if desired. Vhen the sidesections 1S are removed, the bracket 22 may be removed by releasing thebolts 23. The reverse of the operation just described takes place whenthe parts are to be placed in position in the fire-box.

From the foregoing it will be seen that the Darts of the frame may bereadily removed for repairs or for other purposes, that the bricks areretained in position and their lower edges protected, and that provisionis made for the proper expansion of the parts.

Then the corners of the casing are rounding, the side sections 18, asWell as the baseplates 2l of the bracket, may be cut away to conform tothe contour of the casing or otherwise made to fit therein, and where itis found desirable some of the parts maybe dierently constructed or someof the parts dispensed with and others substituted therefor withoutdeparting from the spirit of our invention.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentl. In a device of the character described, aframe comprising interlocking end and side sections adapted to engagethe lower edges of the fire-bricks to retain the same in position, and aremovable hanger and spacing-bar connecting one end of the side sectionsand holding the same in fixed relative positions, substantially asdescribed.

2. A frame for fire-boxes,comprising an end "bar or section providedwith rabbeted ends,

side sections fitting the rabbeted ends of the end section, a bracketforming a support for one end of the side sections, and means forspacing the side sections apart and locking them to the bracket,substantially as described.

3. A frame for fire-boxes, comprising an end section, interlocking sidesections or bars removably engaging the end section, a bracket forming asupport for one end of the side sections, and a hanger formingalocking-bar to rigidly lock the sections together and to the bracket,substantially as described.

4. A frame for fire-boxes,comprisingan end section or bar provided withrabbeted ends, side sections or bars fitting the rabbeted ends of theend section, the said sections having iianges adapted to engage thelower edges of the tire-bricks to retain the same in position andprevent injury thereto, a bracket forming a support for one end of theside seetions and a hanger forming a locking-bar to removably loek thesections together and to the bracket, substantially as described.

5. In a device of the character described, the combination with afire-box casing having lugs thereon to support the fire-bricks, andanend plate havinga pendent fiange and forming a support for the brick orbricks at one end of the fire-box, of a sectional frame adapted toretain the bricks on the lugs and prevent injury to the lower edgesthereof, one member of said frame having a guardbar abutting against thependent flange of the plate, and means for removably locking thesections of the frame together, substantially as described.

6. In a device of the character described, the combination with afire-box casing having means for supporting the fire-bricks therein, ofan interlocking sectional frame adapted to retain the bricks on theirsupports and prevent injury to the lower edges thereof, and a removablehanger serving as aloeking-bar and forming a portion of the frame,substantially as described.
